Collision‐induced photon emissions from 8 ke V O and CO ion beams

Abstract

AbstractThe optical emission spectra between 190 and 680 nm of 8 keV O and CO collisions with He and N2 target gases were obtained and analyzed on a modified commercial VG ZAB‐2F mass spectrometer. Emissions observed were from O, O+, He, N (B2∑+u → X2∑+g) and N2 (C3∏u → B3∏g) in the case of O projectiles and C, CO (B2∑+u, A 2∏u → X 2∏g), CO+· (B2∑+ → X2∑+), N (B2 ∑+g → X2∑g) and N2 (C3∏u → B 3∏g) in the case of CO projectiles. The results are discussed in relation to previous reports on N–target collisions and the collision–induced dissociation mass spectral characteristics of O and CO.
